APPLICATION NOTE How to set up the BP1024COM and BP2024COM chargers without a PC connection

• © The block of 3 DIP switches (micro-switches): selects the charging mode and the battery type (see details below). • © The "Charging Current Adj." potentiometer: adjusts the battery's maximum charging current (see details below). • © The Battery-Start button: powers the loads (DC load output) from the battery without mains (see details below). An external Battery-Start button can also be wired to the 8-pin connector (pins 7 & 8). (See details below.) • © The NTC temperature probe for compensation is wired to the 8-pin connector (pins 3 & 4). (See details below.) • © The LED indicators (DC...

ON = 2 stages (constant current + constant voltage). • DIP 2 and DIP 3 select the presets below according to the battery type. Flooded (liquid electrolyte) Flooded (liquid electrolyte) 1. The BPCOM chargers provide 2 DC voltage outputs: • 1 output for battery charging. The maximum current is 80% of the charger's rated current. • 1 output for powering the DC loads. The current corresponds to the % remaining to reach 100% of the charger's rated current. • Battery current = 2A ^ max. charging current = 8A • Battery current = 5.5A ^ max. charging current = 4.5A • Battery current = 8A ^ max. charging...

Temperature compensation automatically adjusts the charging voltage according to the battery temperature: a cold battery requires a higher voltage, a hot battery a lower voltage. If the probe is not connected, there is no compensation and the set voltage does not vary with temperature. If the probe is connected (fix the supplied NTC sensor on the battery or nearby), the compensation is: To change the +/-36mV per °C setting, it is necessary to connect the PC. LED: three indicators provide status information: • AC Fail (mains loss) • Status (charging state, with flashing codes to signal faults)....
